the, HUM; c mrt having im 'smal diameter (at on the piuma uf .1 nm'nmy2391"-- zu i3 bein le mixing' low throttle 20 the part 2l is shownprovided with a stop 23, in position to enable valve 12 to rise therequired distance, and around said stop are several openings 23a formedbe tween arms or branches 23b of the casting, to which arms the stop 23is connected, which arms or branches are shown 'upwardly and outwardlyinclined. The side surfaces 23c oi said arms are also shown inclinedupwardly at an angle to the vertical. The mixture of liquid fuel and airis caused to travel in several streams through the openings 23, beingdiverted with a sort of swirling motion to more finely break up themixture,

The needle valve 8 may be set for the desired supply of fuel to thecarbureting chamber for ordinary running conditions, and in order toenable said valve to be opened more widely at cer-tain throttleopenings, as when the throttle 20 is wide open or nearly so, I providethe following arrangement: At 24 is an arm adapted to be secured in setposition upon needle valve 8, as by the screw 25 clamping the split endof arm 24 securely upon said needle valve. Between arm 24 and shaft 22 Iprovide devices formoving said arm as required. To this end I have showna rod 26, connected with arm 24, and slidable in a cylinder or bore 27in a member 28 that is connected with the throttle arm 29 secured uponshaft 22 in an ordinary mannei. The rod 2G is connected with arm 24 by asuitable swivel or ball-and-socke-t joint of well known character,indicated at 2G, and the member 28 is similarly connected with arm 29 bya swivel or ball-andsoeket joint 30. The rod 26 is shown screw threadedto lit securely in iiiemberj26at and is shown provided with a stop forthe member 28, said stop being shown in the form of nuts 3l, wherebysaid nuts may be set and secured along rod 26 in desired position toengage the member 2S. The arrangement is silcli that arm 24 may benormally held against a stop 32 by a suitable spring 33, and the rod 2Gwill have free play iii Ibore or cylinder 27 for the full throw ofthrottle arm 29, when the nuts 3l are set at the greatest distance frommember 28, as illustrated in Fig. l, so that in such 1 case the throttle20 may be operated without iii turn operating valve 8. It, however, itis desired to cause valve 8 to open at'or near the termination of thefull opening of throttlc 20, the nuts 3l will be set along the rod 26 asuitable distance to cause said nuts to be engaged by member 28, sooneror later, after throttle 2() has opened to a desired extent, to causearm 24 to be moved to the right Fig. l, to thereby rota-te needle valve8 te more or less move the valve from'. its seat l@ to then admit morefuel to aassage 6. this means an increase of fuel supply to carburetingchamber 2 may be effected to" efr; high speeds of the engine, as forrunning on open or nearly open throttle, without i l'ccting the setposition of needle 3 "for ordinary throttle openings.

Changes may be made in the details of :lo construction and arrangementsof parts shown and described, as the same may be varied, within thescope oit the appended claims, without departing troni lthe spirit ofthe invent-ion.

Having now described my invention what I claim is 1. In a carbureter, aeasing having a fuel chamber, a carbureting chamber, a passage providingcommunication between said 8) chambers, a standard extending toward thecarbureting chamber and having a bore opening at its upper end, a valvehaving a recess receiving said standard and lia-ving a stein. enteringsaid bore whereby said valve 8a' is guided to rise and descend upon saidstem relatively to said passage, and a spring within said bore bearingagainst said stem and normally compressed by said valve.

2. In a carbiireter, a casing having a fuel @o chamber, a rarburetiiigchamber, a passage communicating with the fuel chamber and having anorifice communicating with thecarbureting chamber, a mixing chamber, aseries of arms within the mixing chamber spaced above said orifice andhaving a stop, said ariiis providing spaces therebetween, the sidesurfaces oil said arms being inclined upwardly at an angle to thevertical to divert the mixture flowing from the car we buictiiigchamber, a valve to eoact with said stop, aud a throttle above saidarms.
